HST flare up

Last night at around 18:55 the HST made an unusual pass over my location, it was unusual in that it flared like an Iridium. It was predicted to be 1.8 mag. but it would have been closer to -2.0 and at the flare peek it was around -8.0. I have been reading that sometimes the aft skirt on the telescope can cause this type of reflection just like an Iridium.

Hi Mick, it happened over my location the evening before, in fact it is a regular occurrence, so it pays to look everytime it is passing overhead near sundown,you may gat a big surprise. Also watch for the ISS to do the same thing. astroron

I usually spend more time observing the ISS and Iridium's so I've never see the HST flare. Thanks astroron

Could it be that the double is caused by a manouvering event and that flares from the hst are often a result if this and therefore nor predictable?

Sorry, been away working for a few days. No not a typo it was very bright Ving, it caught me by surprise I knew it was the HST but I didn't expect it to flare. I see on seesat that HST flares can be predicted.
